Tea instead for World's biggest Coffee Morning

Im holding a World's Biggest Coffee Morning for Macmillan on 30th sept but as i'm not a coffee drinker i'm going to supply a variety of teas instead!

Just wondering if anyone else is holding an event this year? or has done last year and if they'd like to give me any tips? Even if you just tell me your top three teas, i'd appreciate it! Want to make my event a hit, raise some money and maybe sample some new flavours
